FUNC
DATA
F14 Restart mode after momentary power failure
This function determines whether operation is restarted upon recovery from momentary power failure:
0
Inactive
Failure while drive is stopped:
The stop status is continued after recovery from the failure.
Failure during operation:
LU indication is held immediately due to undervoltage and the drive
trips with alarm output.
1
Inactive
Failure while drive is stopped:
The stop status is continued after recovery from the failure.
Failure during operation:
LU indication is held upon recovery from the failure and the drive trips
with alarm output.
2
Active
The drive restarts with the frequency at the momentary power failure when 0.5s elapses after recov-
ery from the fail
3
Active
The drive restarts with the starting frequency when 0.5s elapses after recovery from the failure.

Frequency limiter (Low)
This function sets the upper and lower limits of output frequencies.

If the upper limit and lower limit settings are reversed, the upper limit is
valid and the lower limit is ignored.
Hence, the operation is always performed with the upper limit regardless of the frequency setting.
